Quick Summary

Ixodes pacificus, also known as the western black-legged tick, is a type of tick found in the western United States and British Columbia. This tick is a vector for several diseases, including Lyme disease and anaplasmosis.12

Tick-borne diseases, in general, are illnesses transmitted to humans and animals through the bite of an infected tick. The incidence of these diseases has been rising, partly due to climate change, which expands tick habitats and activity seasons. Other diseases transmitted by ticks include babesiosis, Colorado tick fever, Rocky Mountain spotted fever, ehrlichiosis, and tularemia.2
